Claims15
A mobile device with a gas monitor, comprising:
- a gas sensor that measures gas concentration in a volume of gas;
- a mobile device coupled to the gas sensor, the mobile device including a processing unit executing instructions to:
- receive a request from a user of the mobile device;
- if the request is for calibrated data and if a previous calibration has expired,
